Abstract:
One of the principal causes of corrosion of highway bridges is leakage of dissolved deicing chemicals through expansion joints. Waterproof expansion joints for bridges with movements of four inches (101.6 mm) or more present special design requirements which must be met to achieve adequate performance in long term service.
